Decrease in volume and density of foraminiferal shells with progressing ocean acidification
Abstract Rapid increases in anthropogenic atmospheric CO 2 partial pressure have led to a decrease in the pH of seawater. Calcifying organisms generally respond negatively to ocean acidification. Foraminifera are one of the major carbonate producers in the ocean; however, whether calcification reduc...
